2002 Chevrolet Trailblazer Question: Check gauges



Visitor, 3.3L V6, Abbeville, LA, December 23, 2010, 22:49

just noticed that my check gauges light would go on then cut off back and forth. I looked at my gauges and noticed that my oil pressure gauge will be fine then fall then jump back to normal. What do you think?

    When I am idleing it drops , then when I give the gas it jumps back to normal ...... Is an oil pressure switch expensive usually?
